PREFACE 

DURING  the  years  which  have  elapsed  since  Professor  Arthur  M. 
Comey's  admirable  "Dictionary  of  Chemical  Solubilities"  went 
to  press  (March,  1894),  the  literature  upon  solubilities  has  grown 
to  such  an  extent  that  it  has  appeared  desirable  to  make  a  new 
compilation  of  it.  Soon  after  beginning  work  upon  this  volume  the 
author  realized  that  it  would  not  be  possible  to  prepare  a  com- 
pilation of  solubility  results  which  would  fulfill  completely  the 
various  requirements  of  theoretical,  technical,  analytical,  and 
other  classes  of  chemists,  and  he  has  therefore  endeavored  to  meet 
some  of  the  needs  of  all  chemists  rather  than  provide  information 
especially  arranged  for  any  particular  class. 

The  following  features  have  been  considered  of  chief  impor- 
tance in  preparing  the  present  compilation:  completeness  of  the 
data,  reliability  of  the  determinations,  uniformity  in  expression 
of  results,  convenience  of  arrangement  of  material,  and  the  index- 
ing of  the  cross-references  to  tables. 

The  material  has  been  collected  almost  entirely  from  the  origi- 
nal sources,  and  not  from  text-books  or  works  of  reference. 
The  plan  followed  has  been  to  search  diligently  the  tables  of  con- 
tents or  indices  of  twenty -five  of  the  principal  chemical  journals 
issued  since  1875,  and  to  consult  all  articles  in  these  as  well  as  in 
other  journals  to  which  references  could  be  obtained.  In  this 
connection,  however,  it  should  be  stated  that  indexed  references 
to  work  on  solubility  usually  appear  under  the  name  of  the  sub- 
stance employed,  and  not  under  the  heading  "solubility."  Fur- 
thermore, solubility  determinations  are  often  incidental  to  other 
investigations,  and  consequently  are  not  indicated  in  the  title 
of  the  article  or  included  in  the  index  of  the  journal.  Consid- 
ering these  difficulties  there  can  be  little  hope  of  making  such 
a  compilation  complete  in  every  detail,  and  in  the  present  case 
the  best  that  can  be  said  is  that  an  earnest  effort  has  been  made 
to  omit  nothing  of  importance.  This  has  been  done  not  only 
for  the  author's  personal  satisfaction  in  perfecting  the  work, 
but  also  to  give  the  reader  a  reasonable  assurance  that  the  ab- 
sence from  these  pages  of  results  upon  a  particular  substance  is 
good  evidence  that  such  determinations  of  satisfactory  reliability

PREFACE 

are  not  readily  obtainable  from  the  usually  accessible  chemical 
journals. 

Although  at  the  time  Professor  Comey  compiled  his  book  it 
appeared  inadvisable  to  attempt,  in  the  majority  of  cases,  to 
select  the  most  reliable  determinations  of  the  solubility  of  the 
same  substance  reported  by  different  investigators,  the  present 
author  believes  that  this  can  now  be  done  with  advantage.  The 
selections  have  been  made  in  all  cases  by  calculating  the  avail- 
able determinations  to  a  common  basis  and  drawing  curves 
through  the  points  plotted  on  cross-section  paper.  A  comparison 
of  the  curves,  together  with  a  study  of  the  details  of  the  methods 
by  which  the  determinations  were  made  in  the  several  cases,  has 
usually  furnished  clear  evidence  for  a  reliable  selection.  For 
some  substances,  however,  this  plan  could  not  be  followed,  and 
it  has  therefore  been  necessary  to  present  two  or  more  sets  of 
disagreeing  results. 

In  many  instances  the  calculations  and  study  necessary  to 
ascertain  the  most  reliable  figures  have  required  much  labor, 
and  perhaps  in  some  cases  the  author  has  not  succeeded  in 
selecting  the  ones  nearest  the  truth;  but  it  is  believed  that  the 
economy  of  space  required  to  present  the  material,  and  the  saving 
of  the  time  of  the  reader  in  making  the  necessary  selections  him- 
self, will  far  overbalance  the  disadvantage  resulting  from  the 
accidental  inaccuracies  introduced  through  extended  computa- 
tions. 

An  additional  advantage  resulting  from  the  recalculation  of 
different  determinations  to  a  common  basis  is  the  increased 
uniformity  in  the  expression  of  results  throughout  the  volume. 
On  this  account  it  has  been  possible  to  give  the  solubility  of  most 
substances  for  regular  intervals  of  temperature  and  in  terms  of 
weight  of  dissolved  substance  per  given  weight  of  solvent  or  of 
solution. 

Quantitative  results  alone  have  been  included  in  this  com- 
pilation, since  it  is  assumed  that  qualitative  determinations,  if 
desired,  can  be  readily  made  by  simple  tests  in  the  laboratory, 
and  therefore  the  effort  necessary  to  collect  such  observations 
from  the  literature  is  out  of  proportion  to  the  value  of  the  inform- 
ation obtained. 

In  regard  to  the  names  and  formulas  of  the  compounds  in- 
cluded, the  author  wishes  to  say  that  they  are,  for  the  most  part, 
given  as  found  in  the  original  papers  from  which  they  were  taken ; 
and  in  some  cases  a  lack  of  uniformity  in  the  manner  of  their

PREFACE 

expression  will  be  noted.  This  is  especially  true  of  the  molecules 
of  water  of  crystallization  in  the  formulas  given  in  connection 
with  the  guide  names  placed  in  heavy  type  at  the  head  of  the 
tables  for  all  substances  considered.  As  is  well  known,  many 
compounds,  besides  gaining  or  losing  water  in  air,  also  crystal- 
lize with  different  numbers  of  molecules  of  water  even  at  the 
ordinary  temperature,  and  it  was  therefore  thought  best  to  include 
such  information  at  the  proper  place  in  the  tables  under  the 
heading  "Solid  Phase"  rather  than  to  select  in  doubtful  cases 
the  number  of  molecules  of  water  which  the  particular  substance 
was  considered  to  carry  under  ordinary  conditions. 

Although  the  arrangement  of  the  material  is  alphabetical  accord- 
ing to  the  customary  English  names,  an  index  has  been  added 
which  also  provides  for  those  cases  where  there  appears  a  doubt 
as  to  which  name  is  preferable,  and  furnishes  cross-references  to 
those  tables  which  contain  results  upon  more  than  one  substance. 

A  glance  through  the  pages  of  this  book  will  show  the  incom- 
pleteness of  the  data  for  many  of  the  most  common  chemical 
compounds.  Furthermore  many  of  the  results  given  are  of 
doubtful  accuracy,  although  the  best  available.  It  is  hoped, 
therefore,  that  a  realization  of  the  present  incomplete  state  of  our 
information  concerning  solubilities  as  evidenced  in  these  pages 
will  stimulate  investigations  of  many  of  those  substances  which 
have  hitherto  been  studied  incompletely  or  not  at  all. 

This  volume  went  to  press  January  ist,  1907,  and  the  subject 
matter  is  brought  up  to  November,  1906. 

In  conclusion,  the  author  begs  all  indulgence  for  errors  and 
omissions,  and  will  thank  any  one  for  calling  them  to  his  attention 
or  making  suggestions  such  as  would  improve  a  possible  future 
edition  of  this  "Handbook."

NOTE.  —  In  the  original  paper  the  results  are  given  in  terms  of  gram 
molecules  of  acenaphthene,  acetamide,  acetanilide,  etc.,  per  100  gram 
molecules  of  solvent,  at  temperatures  which  varied  with  each  solvent  and 
with  each  weighing  of  the  solutions.  The  tabulated  results  here  given 
were  obtained  by  recalculating  and  reading  the  figures  from  curves  plotted 
on  cross  section  paper.

papers  to  which  references  are  given  in  the  above  tables,  are  reported 
in  millimolecules  per  10  cc.  portions  of  each  layer  in  the  several  cases. 
To  obtain  the  figures  given  in  the  above  tables,  the  original  results  be- 
fore and  after  calculating  to  gram  quantities  were  plotted  on  cross- 
section  paper,  and  from  the  curves  thus  obtained,  readings  for  regular 
intervals  of  concentration  of  acetic  acid  in  the  aqueous  layer  were 
selected.

NOTE.  —  The  above  determinations  were  made  by  adding  successive 
small  quantities  of  acetone  to  mixtures  of  known  amounts  of  water 
and  the  carbohydrate,  and  noting  the  point  at  which  a  clouding  due 
to  the  separation  of  a  second  phase  occurred.  This  method  was  also 
used  for  the  solubility  of  acetone  in  the  aqueous  electrolyte  solutions 
(see  previous  page).  In  the  case  of  the  aqueous  non-electrolyte 
solutions,  however,  successive  small  amounts  of  water  were  added  to 
mixtures  of  known  amounts  of  acetone  and  the  non-electrolyte.

NOTE.  —  Weighed  amounts  of  water  and  acetylacetone  were  placed  in 
small  glass  tubes,  which  were  then  sealed  and  slowly  heated  until  the 
contained  mixtures  became  homogeneous.  The  temperature  was  then 
allowed  to  fall  very  gradually  and  the  point  noted  at  which  cloudiness 
appeared.  This  point  was  accurately  established  for  each  tube  by  repeated 
trials.  The  curve  plotted  from  these  determinations  shows  two  percentage 
amounts  of  acetylacetone  which  cause  cloudiness  at  each  temperature 
below  the  critical  point.  Of  these  two  points,  for  each  temperature,  one 
represents  the  aqueous  layer,  i.e.,  the  solubility  of  acetylacetone  in  water; 
and  the  other  represents  the  acetylacetone  layer,  i.e.,  the  solubility  of 
water  in  acetylacetone.  This  method  is  known  as  the  "  Synthetic  Method," 
and  yields  results  in  harmony  with  those  obtained  by  the  analytical  method, 
i.e.,  by  analyzing  each  layer  after  complete  separation  occurs.

NOTE.  —  The  potassium  alum  figures  in  the  preceding  table  were 
taken  from  a  curve  plotted  from  the  closely  agreeing  determinations  of 
Mulder,  Locke,  Berkeley,  and  Marino.  For  the  higher  temperatures 
(above  60°),  however,  the  results  of  Marino  are  lower  than  those  of 
the  other  investigators,  and  are  omitted  from  the  average  curve. 

Locke  called  attention  in  his  paper  to  the  fact  that  Poggiale's  results 
upon  ammonium  and  potassium  alum  had  evidently  become  inter- 
changed through  some  mistake.  This  explanation  is  entirely  sub- 
stantiated, not  only  by  Locke's  determinations,  but  also  by  those  of 
Mulder  and  Berkeley.  The  ammonium  alum  figures  given  above  were 
therefore  read  from  Poggiale's  potassium  alum  curve,  with  which 
Locke's  determination  of  the  solubility  of  ammonium  alum  at  25°  is  in 
entire  harmony.

NOTE.  —  When  ammonium  sulphate  is  added  to  aqueous  solutions 
of  alcohol,  it  is  found  that  for  certain  concentrations  and  temperatures 
the  solutions  separate  into  two  liquid  layers,  the  upper  of  which  con- 
tains the  larger  percentage  of  alcohol. 

Most  of  the  determinations  which  have  been  made  upon  this  system, 
as  contained  in  the  papers  referred  to  above,  are  given  in  terms  of 
grams  of  ammonium  sulphate,  of  alcohol  and  of  water  per  ioo  grams 
of  these  three  components  taken  together.  Those  results  which  are 
given  in  other  terms  can  be  readily  calculated  to  this  basis,  and  it  is 
therefore  possible  to  make  a  comparison  of  the  several  sets  of  de- 
terminations by  plotting  on  cross-section  paper  and  drawing  curves 
through  the  points.  In  the  present  case  the  grams  of  alcohol  per  ioo 
grams  of  solution  were  taken  as  ordinates,  and  the  grams  of  ammo- 
nium sulphate  in  the  same  quantity  of  each  solution  taken  as  abscissae. 
It  was  found  that  a  single  curve  could  be  drawn  through  practi- 
cally all  the  points  representing  the  upper  layer  solutions  at  the 
several  temperatures,  but  the  points  for  the  solutions  containing  the 
larger  amounts  of  water  gave  curves  which  diverged  with  increase  of 
temperature.  The  results  given  for  33°  in  the  above  table  are  not 
to  be  accepted  as  correct  until  further  work  has  been  done.

SOLUBILITY  OF  ANTHRAQUINONE  IN  ETHER.

Weighed  amounts  of  ether  and  anthraquinone  were  placed  in  glass 
tubes  which  were  then  sealed.  The  temperature  noted  at  which  the 
anthraquinone  disappeared  and  also  at  which  the  liquid  phase  disap- 
peared (critical  temp.).  The  two  curves  cross  at  195°  and  again  at 
241°.  Between  these  two  temperatures  the  critical  curve  lies  below 
the  solubility  curve,  hence  for  this  range  of  temperature  no  solubility 
curve  is  shown.  The  following  figures  were  read  from  the  curves,  and 
are  therefore  only  approximately  correct.

NOTE.  —  The  effect  of  the  presence  of  certain  chlorides  upon  the 
decomposition  of  cadmium  tetra  potassium  chloride  by  water  at  16° 
was  investigated  by  Rimbach  in  a  manner  similar  to  that  used  in  the 
case  of  cadmium  tetra  rhubidium  chloride  (see  preceding  page).  The 
results,  which  show  the  extent  to  which  increasing  amounts  of  the 
several  chlorides  force  back  the  decomposition  of  the  double  salt,  were 
plotted  on  cross-section  paper,  and  the  points  at  which  the  decom- 
position was  prevented,  were  determined  by  interpolation.  These 
values  which  show  the  minimum  amount  of  the  added  chlorides  which 
must  be  present  to  insure  the  crystallization  of  the  pure  double  salt  are 
shown  in  the  following  table.

In  the  second  series  a  very  much  larger  excess  of  lime  was  used  than 
in  the  first  series.  The  author  gives  results  in  a  subsequent  paper,  — 
Bull.  soc.  chim.  [3]  23,  740,  'oo,  — which  show  that  the  solubility  is  also 
affected  by  the  condition  of  the  calcium  compound  used,  i.e.,  whether 
the  oxide,  hydrate,  or  milk  of  lime  is  added  to  the  sugar  solutions.

CALCIUM    PHOSPHATE    (Tribasic)    Ca3(PO4)2. 
SOLUBILITY  IN  WATER. 

The  determinations  of  the  solubility  of  this  salt  in  water,  as  stated 
in  the  literature,  are  found  to  vary  within  rather  wide  limits,  due,  no 
doubt,  to  the  fact  that  so-called  tribasic  calcium  phosphate  is  apparently 
a  solid  solution  of  the  dibasic  salt  and  calcium  oxide,  and  therefore 
analyses  of  individual  samples  may  show  an  excess  of  either  lime  or 
phosphoric  acid.  When  placed  in  contact  with  water,  more  PO4  ions 
enter  solution  than  Ca  ions,  the  resulting  solution  being  acid  in  reaction 
and  the  solid  phase  richer  in  lime  than  it  was,  previous  to  being  added 
to  the  water.  For  material  having  a  composition  approximating 
closely  that  represented  by  the  formula  Ca3(PO4)2  the  amount  which 
is  dissolved  by  CO2  free  water  at  the  ordinary  temperature,  as  cal- 
culated from  the  calcium  determination,  is  o.oi  to  o.io  gram  per  liter, 
depending  upon  the  conditions  of  the  experiment.  Water  saturated 
with  CO2  dissolves  0.15  to  0.30  gram  per  liter. 

A  list  of  references  to  papers  on  this  subject  is  given  by  Cameron 
and  Hurst  —  J.  Am.  Chem.  Soc.  26,  903,  '04;  see  also  Cameron  and

q  *=  wt.  of  gas  dissolved  by  i  oo  grams  of  solvent  at  a  total  pressure  of  7 60  mm. 

p  =  the  Bunsen  Absorption  Coefficient  which  signifies  the  volume  (v)  of 
the  gas  (reduced  to  o°  and  760  mm.)  taken  up  by  unit  volume  (V)  of  the  liquid 
when  the  pressure  of  the  gas  itself  minus  the  vapor  tension  of  the  solvent  is 
760  mm.  _  v 

*  =  V(i  +  0.00367  i)  ' 

I  =  the  Ostwald  Solubility  Expression  which  represents  the  ratio  of  the 
volume  (v)  of  gas  absorbed  at  any  pressure  and  temperature,  to  the  volume 

(V)  of  the  absorbing  liquid,  i.e.  /  =  p  •      This  expression  differs  from  the 

Bunsen  Absorption  Coefficient,  p,  in  that  the  volume  (v)  of  the  dissolved  gas 
is  not  reduced  to  o°  and  760  mm.  The  solubility  /  is  therefore  the  volume 
of  gas  dissolved  by  unit  volume  of  the  solvent  at  the  temperature  of  the 
experiment.  The  two  expressions  are  related  thus: 

/  =  p  (i  +  0.00367  /),      p  =  - — ; — .

The  saturated  aqueous  solution  of  the  chlorine  was  cooled  until 
chlorhydrate  separated;  the  temperature  was  then  gradually  raised 
and  portions  withdrawn  for  analysis  at  intervals.  Slightly  different 
results  were  obtained  for  solutions  in  contact  with  much,  little,  or  no 
chlorhydrate.  The  following  results  are  taken  from  an  average

IRON    PHOSPHATE    Fe2(PO4)3. 

THE  ACTION   OF  WATER  AND   OF  AQUEOUS   SALT  SOLUTIONS   UPON 
FERRIC  PHOSPHATE. 

(Lachowicz  —  Monatsh.  Chem.  13,  357,  '92;  Cameron  and  Hurst  —  J.  Am.  Chem.  Soc.  26,  888,  '04.) 

The  experiments  show  that  the  ordinary  precipitation  methods  for 
the  production  of  ferric  phosphate  give  products  which  do  not  conform 
to  the  formula  Fe2(PO4)3.  By  digesting  such  samples  with  water 
very  little  is  dissolved,  but  the  material  is  decomposed  to  an  extent 
depending  upon  the  relative  amounts  of  solid  and  solvent  used.  The 
amount  of  PO4  dissolved  per  gram  of  Fe2(PO4)3  varies  from  about 
0.0026  gram  removed  by  5  cc.  H2O  to  0.0182  gram  removed  by  800  cc. 
H2O  at  the  ordinary  temperature.

NOTE.  —  In  the  original  paper  the  author  writes,  "  grams  of  sub- 
stance in  zoo  grams  of  solvent  (percentage  solubility)  "  and  "  moles 
of  substance  in  100  mols  of  solvent  (percentage  molar  solubility),"  thus 
implying  equivalence  of  the  terms  and  giving  rise  to  uncertainty  as  to 
which  is  really  intended.

NOTE.  —  Since  the  acid  salt  is  less  soluble  at  ordinary  temperatures 
than  the  neutral  salt,  it  can  be  precipitated  from  the  solution  of  the 
neutral  salt  by  addition  of  aqueous  formic  acid.  Proceeding  in  this 
way  an  impure  product  is  obtained,  giving  solubility  values  (expressed

NOTE.  —  Cohn  shows  that  the  lower  results  obtained  by  Valenta 
are  due  to  the  excess  of  solid  AgBr  used  and  the  consequent  formation 
of  the  less  soluble  di  salt  3(AgS2O3Na)2  instead  of  the  more  soluble 
salt  (AgS2O3Na)2Na2S2O3.

Above  45  cc.  acetone  per  100  cc.  solvent  the  solution  begins  to 
separate  into  two  layers.  The  lower  of  these  contains  51  gms.  sugar 
per  100  cc.  and  has  Sp.  Gr.  1.1522.  The  upper  layer  contains  so 
little  sugar  that  the  amount  could  not  be  determined  by  the  method 
employed.  100  cc.  evaporated  in  a  vacuum  desiccator  left  a  residue 
of  3.68  gms.  Above  the  concentration  of  80  cc.  acetone  per  100  cc. 
solvent  the  two  layers  unite.  In  pure  acetone  100  cc.  solution  give

ADDENDUM 

The  distribution  results  shown  in  the  following  table  were  obtained 
by  agitating  together  equal  volumes  of  olive  oil  and  aqueous  solutions 
of  the  several  narcotics,  and  determining  the  dissolved  substance 
present  in  the  aqueous  layer  before  and  after  the  agitation.  The  sum 
of  the  amount  of  substance  in  the  oil  and  aqueous  layers,  as  shown 
in  the  table,  is  the  amount  originally  in  100  cc.  of  each  aqueous  solu- 
tion used. 

The  work  was  done  for  the  purpose  of  testing  the  Overton-Meyer 
Theory  of  Narcosis,  that  the  anesthetic  action  of  certain  groups  of 
narcotics  is  proportional  to  their  distribution  between  water  and  the 
fatty  material  occurring  in  the  nervous  system,  and  olive  oil  was 
selected  as  the  solvent  best  fulfilling  the  analytical  requirements 
and  at  the  same  time  offering  a  fair  resemblance  to  the  fatty  substance 
of  the  nervous  system.  The  results  are  believed  to  be  of  interest 
both  as  solubility  studies  and  on  account  of  their  connection  with 
the  Theory  of  Narcosis. 

The  author  is  indebted  to  Dr.  Reid  Hunt  of  the  Hygienic  Laboratory 
for  calling  his  attention  to  the  papers  containing  the  distribution 
results  here  tabulated.
